Downloaded play-2.0 from type safe yesterday, following instructions as far as I can, but when I come to build with sbt I get unresolved dependency errors: [warn] :: org.slf4j#slf4j-api;1.6.1: configuration not found in org.slf4j#slf4j-api;1.6.1: 'compile'. It was required from org.hibernate#hibernate-validator;4.2.0.Final compile [warn] :: commons-codec#commons-codec;1.4: configuration not found
